Application filed March 18, 1914. Serial No. 825,594.

To all whom it may concern:

Be it known that 1, HENRY A. WISE W001), a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Printed and Sli Sheet SeparatingApparatus, of which t e following is a specification.

The object of this invention is to provide an apparatus by which a pileof sheets consisting of printed sheets and slip-sheets can be separated,the printed sheets put in a flat pile or passed to a folder or othersheet manipulating apparatus either side up, and the slip sheetsdeposited in a pile by themselves ready for use again.

Referring to the drawings and in detail, Figure 1 is a side elevation ofone form of my apparatus. Fig. 2 is a side elevation on an enlargedscaleof part of the apparatus shown in Fig. 1. Fig. 3 is across-sectional view taken on the line 33 of Fig. 2. Fig. 1 is a sideelevation taken on the side opposite to the view shown in Fig. 2, andFig. 5 is a diagrammatic view illustrating a modification which may bemade in the general arrangement of the apparatus.

Referring to the drawings, an apparatus is shown wherein the printedsheets can be delivered flat with either the last printed side up .ordown as desired.

In said drawings A designates a. pile of interposed printed andslip-sheets. This pile is laid upon a suitable table 20 and the sheetsare fed one at a time from said pile either by any of the usualautomatic feeders or by hand. The apparatus for manipulating the sheetsthus fed is arranged between two side frames 2121. The sheets as theyare fed first pass in between two sets of tapes, an upper set 22 and alower set 23. The upper set of tapes is trained around tape pulleys 96and 97 continuously driven by any suitable means, not necessary to show,so that the said tapes 22 will run continuously in the directionindicated by the arrows. The lower set of tapes 23 is trained round tapepulleys 28. Then the tapes pass around a roller 32 j ournaled incarriers cc, and then around pulleys 3334 and 36 back to thepulleys 28.The pulleys 33 and28 are arranged on shafts which are journaled in theside frames 21-21. The pulleys 34 and 36 are mounted on shafts 340 and360 respectively, which are journaled in frames or welghts 37 which arefitted to slide on ways .38 formed 01' secured to the side frames 21-21.By this arrangement, as the tape roller 32 is reciprocated by the meanshereinafter described, a constant tension will be kept on the tapes 23.

The carriers c--c for the roller 32 are arranged so as to be capable ofa reciprocating motion on ways 515 formed or secured to the side frames2 21. These carriers c-c are provided with rollers 52 to run on saidways. The carriers are reciprocated by means of a crank-pin 53 mountedon a disk 54 which crank-pin connects by link 55 to a lever 56 mountedon a shaft 57 journaled in the side frames 21-21. Arms 5858 are securedto said shaft 57, and each carrier 0 is connected by a' link 59 to oneof said arms 58. The disk 54 is geared as hereinafter described to turnonce for each sheet and slipsheet manipulated in the machine, and bythis arrangement, the carriers cc will be reciprocated once for eachsheet and slipsheet.

The shaft of the roller 32 is loosely journaled in the carriers cc, andloosely arranged on the shaft is a gear 60 which meshes with a rack 61out or formed on the underside of one of the ways. A ratchetwheel 62 issecured on the end of the shaft of the roller 32, and engaging theratchetwheel is a pawl 63 pivoted on the gear 60, which pawl is held inengagement with the ratchet-wheel by a spring 64. By this arrangement,as the roller 32 moves forward or to the right, theroller 32 will not beturned as the pawl will run idly around the ratchet-wheel, but when theroller 32 is moved in the opposite direction, the same will be rotatedby the mechanism described to peel the tapes 23 from under the slipsheetto allow a delivery of the same. 7

The roller 32 will deliver the slip-sheets upon a delivery table B. Thisdelivery table is provided with wheels 65 which run on tracks 66extending laterally of the mechanism. By this arrangement, the deliverytable can be slid in or withdrawn laterally of the machine. The deliverytable is provided with bars 67 which project from each corner. Thesebars are engaged by loops formed in the end of cables 68, there beingtwo cables on each side of the machine. The

longest cable at tends over a pulley 69, and the two cables at each sideof the machine are trained over concentric pulleys 70-70, and aresecured at their ends to a drum 71 arranged on the .end of a shaft 72,there thus being two shaft 78 which carries a worm-wheel 79, en-

gaging which is a worm 80 secured on the end of a shaft 81. Adjustablysecured on the shaft 81 is a friction disk 82 which bears on the side.of a large gear 83 mounted on a shaft 84. By adjusting the frictiondisk on the shaft 81 th rate of descent of the table B can be adjusted.The worm wheel 76 is loosely arranged on this shaft, and the same hassuitable projections 85. A handle is-keyed on the end of the shaft 75,and is held normally in engagement with the projections 85 by a spring,not shown, whereby the worm 76 will normally drive the shaft 75. Powermay be applied to the apparatus described by means of a driving beltpassing around a driving pulley 91 arranged on a shaft 92 and carrying apinion 93 meshing with the gear 83 previouslv referred to.

Intermingled with the lower set. of tapes 23 is a set of fly-fingers 98which are secured on a shaft 99 journaled in the framing.

These fly fingers are operated to take the sheet passing out on thetapes 23- andturn I the same over and deliver the same on the deliverytable C arranged substantially in the same manner as the delivery tableB. The delivery table B is slid forward or toward the front from theposition shown in Fig. 1 for delivery, and the table C is pushed in theopposite direction. The table C is lowered by su plemental cables 100from the drums 71- 1 in the same manner as the A pinion 101 is arrangedon the rear end of the shaft 84:, and the same meshes with and engages agear 102 turning loosely on a stud shaft 103 and carrying a cam 104.Engaging the groove of this cam is a roller mounted on a pivoted lever105 secured on the end of a short shaft 106 journaled in a bracketprojecting from the framing. On

the other end of the shaft 106 is arranged a lever 107 pivoted to theend of which is a rack 108 which engages a gear 109 secured on the endof the fly-finger shaft 99. The rack 108 is kept in engagement with thegear 109 by a roller 110. The reduction between the pimons 101 and 102is two to one.

each side of the machine ex- It will be noted that the cam 104 is madeconcentric for about one-half of its periphery, and only has operativesections for the other half of its periphery.

In operation, the delivery table is run on its rails in position in themachine, and the cables 68 are engaged therewith. The handle 86 is thenpulled out so as to clear the projections 85, and the shaft 75 is turnedto its highest position. Then the handle 86 is released so that theworm-wheel 76 will be locked to the shaft 75 and then as the machineoperates, the delivery table B will be lowered as the pile ofslip-sheets accumulates thereon, until it comes down to its rails, whenit is slid laterally out of the machine to remove the slip-sheets. Bythis mechanism a large pile of slip-sheets can be delivered withoutstopping the machine, and the delivery of each sheet takes placeaccurately in the same position, owing to the automatic lowering of thedelivery table. The adjustable friction disk provides for an adjustmentso that this lowering of the delivery table can be timed accurately tothe delivery of the slip-sheets. The first sheet passing between thetapes- 22 and 23 is carried out over the delivery table B. Suppose thefiy-fingers 98 are under the set of lower tapes 23 as this action takesplace. Just as the pulley 32 reaches the end of its forward movement,and as this sheet reaches the end of its forward movement on said tapes23, the fly-fingers" will come into operation, and the sheet will belifted by said fly-fingers, turned over, and delivered on the deliverytable C. The fly-fingers, by reason of'the construction of the camdescribed, will remain in delivery position as the next sheet passesinto the apparatus between the tapes 22 and 23, and as the same isadvanced over the deliver table B, the fly-fingers will not be under t esame. Therefore, durin the backword or left-hand movement 0 the pulleys32 this second sheet will be delivered on the table B. Thus the firstsheet will be turned over and delivered on the table C, while the secondsheet will be delivered on the table B without being turned over. Thusif it is desired to turn over and deliver the printed sheets, the feedis timed so that the printed sheets will be deposited upon the table C,and the slip-sheets on the table B; while on the other hand, if it isdesired to deliver the printed sheets without turning the same over, thefeed is timed so that the printed sheets will be delivered on thedelivery table B and the slip-sheets on the table C.

This apparatus can be employed to great advantage when the sheets areprinted upon lit) meaeea with their unprinted sides up. After the sheetshave been perfected they may be separated from the slip-sheets witheither.

side up as desired for the further manipulation of the sheets. Thisoperation can well be carried out as it is practically immaterial Whichside up the slip-sheets are used, but if the above operation is carriedout in connection with perfecting sheets, it will be noticed that theslip-sheets will be turned over once for every two separations from theI will deliver the sheets thereon, the printedsheets may be passed tothe folder, or by turning the folding apron up as shown in dotted lines,the printed or slip-sheets may be delivered on the tableC. This is anadvantageous arrangement when it is desired to finally fold the printedsheets after they have been perfected.

Many other modifications may be worked out without departing from thescope of my invention as expressed in the claims;

Although I have illustrated and described only a single form of theinvention I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims.

Therefore, I do not wish to be limited in these respects, but

What I do claim is 1. An apparatus for separating intermingled printedand slip-sheets, comprising means for advancing sheets, a sheet deliverymechanism, means whereby the same will act to deliver every alternatesheet, and a second delivery mechanism arranged to deliver the othersheets the opposite side up as compared with the first deliverymechanism.

2. An apparatus for separating intermingled printed and slip-sheets,comprising means for advancing sheets, a sheet delivery mechanism, meanswhereby the same will act to deliver certain sheets in regular order,and a delivery mechanism arranged to turn over and deliver the othersheets.

3. An apparatus for separating intermingled printed and slip-sheets,comprising means for advancing sheets, a reciprocating sheet deliverymechanism, means whereby the same will act to deliver every alternatesheet, a fly delivery mechanism arranged to act on the other sheets, anda folding mechanism. v

4. lnanapparatus for separating intermingled printed and slip sheets,the combination of means for moving the sheets one at a time along apath, means for delivering certain of said sheets, and means forautomatically intercepting a sheet at regular intervals, preventing itfrom passing to said delivering means, and delivering it the othersideup.
